What is a potential risk of an athlete utilizing supplements without professional guidance?

Utilizing supplements without professional guidance can lead to potential health risks due to various factors, including the lack of proper knowledge about dosage, interactions with other substances, and the athlete's unique health conditions or needs. Supplements can contain potent ingredients that might have side effects, or they could interact negatively with medications or other supplements. Without the oversight of a qualified professional, athletes may inadvertently choose products that contain harmful substances or incorrect dosages, putting their health and performance at risk. Additionally, the absence of tailored advice means that the athlete may not benefit from the intended effects of the supplements, further emphasizing the importance of professional guidance in their use.
